The GaussianEditor algorithm, proposed jointly by Nanyang Technological University, Tsinghua University, and SenseTime, has successfully addressed the long-standing issues of time-consuming and low controllability in the field of 3D editing. By adopting Gaussian splatting representation, introducing Gaussian semantic tracking, and hierarchical Gaussian splatting, the algorithm achieves precise and controllable editing, along with a local repair algorithm. This method surpasses previous work in terms of visual quality, quantitative metrics, controllability, and generation speed, providing a powerful tool for future virtual reality and game development.
